(possibly of imitative origin, but debatable) English language vulgarism most commonly used in reference to flatulence. Onomatopoeia for farts have been suggested in various internet forums in response to questions of people who needed a word to describe the sound: eg. here and here. The suggested words include brrt, braaah, THPPTPHTPHPHHPH (Calvin and Hobbes), phhhhhhrt, PPPPPPPPPPPPPPPPPPPPPPPPPPP, pff, prtrtrtrgurtrufnasutututut, prrrt, PFFT!, PHHhhhh..., SPLPLPLLLP, WHOooooffff, poot, prrrrrrrvt, scraeft, ppppppwwarrrrppppp, pllllllllllllllllllllllllloooooooooooaaa..., RRRRRRRIIIIIIIIIIIIIIIIIIIIIIIIIPPPPP, fuuuuuuuuuuuurrrrrrrt, thhhppbbbb, verrrrrrrrrnnnnnntttttt, hooooooooooooooooooooooooonk, pbpbpbpbp, frr frr frrrrrr rampooooooooo ag, pppppppptttttttttttttttttttttttt, flurpppppppppppppppppppppppppppppppppppp... Also, according to many responders it depends on the fart (farting can make many possible sounds).
